Repetição do nome em \textapud

O seguinte exemplo ilustra o caso:
```
\begin{filecontents*}{textapud.bib}
@article{collier09,
author={C. Collier},
title={AAA},
journal={BBB},
year=2009,
}
@article{doe2004,
author={J. Doe},
title={DDDD},
journal={CCC},
year=2004,
}
@article{doe2006,
author={J. Doe},
title={EEE},
journal={FFF},
year=2006,
}
\end{filecontents*}
\documentclass{article}
\usepackage[backend=biber,style=abnt,ittitles]{biblatex}
\addbibresource{textapud.bib}
\begin{document}
\apud{doe2004,doe2006}{collier09}\\
\textapud{doe2004,doe2006}{collier09}
\printbibliography
\end{document}
```
Onde obtemos como resultado:

(DOE, 2004; 2006 apud COLLIER, 2009)
Doe; Doe (2004; 2006 apud COLLIER, 2009)

Note que ```\apud``` tem o comportamento correto, enquanto ```\textapud``` repete o nome.

The issue is in the biblatex-abnt package, specifically the \textapud command. Look at the package source files, likely biblatex-abnt.def or biblatex-abnt.cbx, to find the definition of \textapud and compare it with \apud. The example shows a minimal test case; compile it to reproduce the bug. The fix involves modifying the command to avoid repeating the author name when multiple works by the same author are cited.
